In this return-to-Mars episode, Andrew welcomes Steve Bullock and Maddy Smith to the Shed to talk about the film of the book that we loved back in episode six.

Steve talks to Dr Elliot Sefton-Nash about his work on the new Mars Rover, water on Mars, and music to listen to on the Red Planet, and from Andy Weir about his forthcoming follow up to the Martian.

We also enthuse about miraculous Mars robots, gaffer tape, the complexities of the Rich Purnell Manoeuvre, and the way the film captures the problem-solving essence of the book, and talk about the practicalities and politics of sending humans to Mars.
